- bool "PS3 Wireless private PSK interface (OBSOLETE)"
- depends on GELIC_WIRELESS
- select WEXT_PRIV
- help
- This option retains the obsolete private interface to pass
- the PSK from user space programs to the driver. The PSK
- stands for 'Pre Shared Key' and is used for WPA[2]-PSK
- (WPA-Personal) environment.
- If WPA[2]-PSK is used and you need to use old programs that
- support only this old interface, say Y. Otherwise N.

- If unsure, say N.

- * XXX: This is temporary!
- *
- * The problem here is that when we get here, the driver will
- * quite likely have pretty much overwritten info->control by
- * using info->driver_data or info->rate_driver_data. Thus,
- * when passing out the frame to the driver again, we would be
- * passing completely bogus data since the driver would then
- * expect a properly filled info->control. In mac80211 itself
- * the same problem occurs, since we need info->control.vif
- * internally.
- *
- * To fix this, we should send the frame through TX processing
- * again. However, it's not that simple, since the frame will
- * have been software-encrypted (if applicable) already, and
- * encrypting it again doesn't do much good. So to properly do
- * that, we not only have to skip the actual 'raw' encryption
- * (key selection etc. still has to be done!) but also the
- * sequence number assignment since that impacts the crypto
- * encapsulation, of course.
- *
- * Hence, for now, fix the bug by just dropping the frame.
+ * This skb 'survived' a round-trip through the driver, and
+ * hopefully the driver didn't mangle it too badly. However,
+ * we can definitely not rely on the the control information
+ * being correct. Clear it so we don't get junk there, and
